1 Claim. l

Our present invention relates to beaded mock welting and moreparticularly to an ornamental and seam-lling beaded mock welting adaptedfor use with footwear of the McKay type of construction, and especiallydesigned so that the bead will be automatically forced against the shoeupper by the normal pressure of a foot in the finished shoe.

At present, in footwear of the several McKay types in which the outsole,or the outsole and McKay welt or midsole, are united to a prelastedupper and insole by thru-and-thru stitching, it is generally found thatthe inseam stitching has a tendency to show or grin and thus detractfrom the appearance of the nished shoe. Such stitch grinning becomesfurther apparent in McKay footwear after the shoes have been worn forsome time, as the upper tends to stretch away from the sole, thuspresenting a most objectionable appearance.

It is to obviate this difficulty, therefore, and to assure an attractiveappearing shoe that we have developed our novel beaded mock Welt whichis appropriately designed to be incorporated in any and all types ofMcKay shoes.

Heretofore, various efforts have been made to employ devices which wouldconceal the inseam stitches to prevent them from showing, but such priordevices have included extra strips, made of rubber or the like, whichhave proven unsatisfactory in use and expensive in cost, and also rubberrapidly deteriorates.

We appreciate that welts for use in Goodyear welt footwear have beenmade with beading as an integral part thereof for purposes ofornamentation, and even beaded strips alone, but as far as we areadvised no beaded mock welting has heretofore been developed that may beeffectively applied to footwear of the McKay type of construction.

From the experience gained in extruding resilient and stitchretainingplastic welting for Goodyear welt shoes, we have determined that anyshape of configuration of such plastic material may readily andaccurately be supplied. Accordingly, for specific adaption to McKayfootwear, we have designed a novel and useful beaded mock welt which canbe applied to any shoe of McKay type construction, combines ornamentaland seam-filling characteristics, and is so arranged that the beadportion thereof will be automatically held under pressure against theoutside of the shoe upper.

In carrying out our inventioinwe prefer to arrange our mock Welt with athin stitch-retaining body portion suitably tapered to approq priatelyfill in the seam between the upper and the outsole, welt, or midsole.Integral with the body portion and upstanding therefrom substan tiallyat right angles, we devise our novel curved bead, formed With'a convexouter surface which depends slightly below the lower surface of the bodyto provide a tensioning rib portion, and with a concave inner surface ofproper contour to approximate that of the marginal edge of a shoe upper,the top of said concave surface merging with the upper end of saidconvex sur--jA face to afford an inturned ange to bear tightly andsnugly against the Vouter surface of the upper.

We find that the combination of the resilient characteristics of thematerial and the construction of the bead is particularly effective incausing our mock welt to closely hug the upper when applied to a shoe,as downward pressure exerted on the upper surface of the body portionwill apply force on the lower rib of the bead,v thus setting up a rotarymoment, thereby forcing the inturned flange against the upper and'lretaining the same in pressured Contact with the upper.

Inasmuch as we prefer to make our novel mock welting of syntheticplastic material, we are enabled to turn out a uniform product, at aneconomical cost, and of any desired color. In addition, the inherentresilience of such material is peculiarly suited to an ornamental,moisture-proof, and seam-filling beaded mock welt to improve theappearance, fit, and comfort of the footwear of McKay type construction.

Further features, objects, and details of construction will behereinafter more fully pointed out in the accompanying description andmore clearly defined in the appended claim.

Referring to the drawings showing a preferred embodiment of ourinvention:

Fig. 1 is a perspective view of a strip of our novel beaded mockwelting;

Fig. 2 is a fragmentary cross-sectional view illustrating our novel mockwelt, with the bead slightly overdrawn, applied to a McKay type shoeembodying a Welt and outsole construction;

l Fig. 3 is a fragmentary cross-sectional view illustrating our novelmock welt with the bead slightly overdrawn, applied to a McKay type shoehaving a midsole and outsole construction, and `Fig. 4 is a fragmentarycross-sectionalview illustrating our novel beaded mock Welt, with thebead slightly overdrawn, applied to a nailed McKay shoe.

As shown in the drawings, our novel beaded,

mock Welt, designated generally as IU, consists in a unitary strip ofresilient synthetic plastic material especially designed with arelatively thin attaching body portion II and an ornamental andseam-filling bead portion I2 integral with said body II and curvedupwardly at subst-ahr where the same meet the corresponding, ends of"the bead I2.

Such body II presents an ideal. stitching, surface, and the taperenables it. to. be more easily guided into stitching positionY and to beVmore snugly tted in the seam between the outsole,y and upper, Welt andupper, or midsole and upper,

depending on the type of McKay construction-V involved.

The bead I2 is of greater thickness than the Y body U. and designed.with, convex, exterior and concave interior surfaces-the curves ofkvsaid sursfaces being substantially parallel thru .11h52, medial portionof their respective arcs,` and the exterior surface, having. inturnedupper and lower edge portions to. provide said bead l2. with aY lowerpressure-leverage rib L4. andan upper contacting iiange, 15asshownl Thebead I2. hasbeeh thus. arranged so that. downward pressure on the bodyportion. ll adjacent, the rib Ill results in corresponding reaction on.the. ribI Ifl tocause the Ilan-geY I5 tobe automatically pressed inalateral direction against the upper.

In Figs. 2, 3, and 4 We have illustrated ourV beaded., mock welt inattached, relation with, several modifications of McKay shoeconstruction, Ineachof such modications an upper IS., having the usuallining Il attached the-rein, is lasted to. an insole i8, which lastingmay be eiected by tasking, stapling, or, as here shown, by ceinentingv`Inv Fig.k 2 theupper I5 and they insole It are assembled on a last, andcernentflasted together. Thereupon, the last` is` withdrawn,` and ourmock, welt I0, together with the McKay welt 20, simula. taneously fedabout` the. lastedl edge oi the upper L6. by suitablel guides as the`thru-and-thruA in. seam stitching, indicated at 2l., is set.

Following ther inseam-stitching operation, the outsole 22 is thenapplied and secured by a line of outseam stitching 2,3 thru the welt 2i)and outsole 22V adjacent the outer edges thereof. The usual finishingoperations are' then performed and the shoe completed,

In Fig. 3,` we have depicted our beaded mock Wel-t I0, applied to a McKashoe of the type embodying a midsole and outsole construction. In thisform, the upper I5 and insole I3 are assembled on a last as above,cement-lasted together, and the last4 Withdrawn. Thereupon, our mockwelt I0. is fed by suitable guides about the lasted edge of the upper Itas the thru-andthru stitching 25 is set, uniting the insole IB, upperI6, and body portion Il. A midsole 25 is then prepared and secured tothei above by a further line ci inseam stitching 21, after which an.outsole 28 is.v incorporated therewith by means of outseam stitching2.9- set thru the outer edges of said midsole 25 and outsole 29,. Asabove.- the usual finishing operations are then, performed and the, shoecompleted.

In Fig. 4, wev have shown our beaded mock welt I applied toa shoe of thesoscalled straight McKay type of construction. Similarly, in thismethodthe upper I and insole I8 are rstassembled on a last and bonded togetherby cement- It lasting. VVThe last 1s then withdrawn, and our mock weltI0 suitably guided about the lasted edge of the upper I6 as thethru-and-thru inseam stitching, indicated at 30, is set, thus uniting.theuppel I6,` insole I8.^ ahdhody II of our mock Welt III.V

As thus far assembled, the shoe is thereupon re-lasted and the outsole3| attachedV thereto by a line of tacks 32 which are readily driven thruthe sole 3l', body II of the mock welt I0, upper I6 and insole I8, andclinched over against the, lastv bottom, as,` shown. And, again, as inVthe other formsI described, the shoe is now in readiness for the usualfinishing operations.

From the foregoing, it will be apparent that our invention may bereadily adapted to various types of McKay shoe constructions,functioning as an, ornamental, seam-filling, andmoistureproof element.The tapered body portion II ideally arranged to ll the, inner spacebetween the lasted upper and the. sole elements, while the. constructionof the bead l2 adequately fills the outer seam therebetween and conceaisthe stitching. Asv shown Figs. 2, 3 and e, the tightening action of thestitches 2l, 2t, and respectively, is sufficient to .flatten out the rible, thus creating enough pressurev on the fia-nge il so, that it willhug the marginal' edge of the upper lil in moisture-tight association.The resilient, and yielding characteristics or the syn. thetic plasticmaterial are, of ,thev utmostA iinportance in making our beaded mockwelt so. useful,v serviceable, ecient, and comfortable to the wearer,and the fact that suchv material is waterproof and may be produced in,any color adds to the allearound value of our product.

While. our beaded mock welt, as above ex plained, is directed for usewith footwear of the McKay type of construction, we do not wish to belimited thereby as our invention could well be adapted to other types ofshoe construction.
